A Journey through Serverless & IoT on AWS
Non working battery pack, corroded and leaking cells 😦
New LG 18490 cells in place 😉
Arduino based charge/discharge cycle tester.
The ERS-220 has a much more robotic look and was always the one that I really wanted, just because of how cool he looks. He has several blue and red LEDs and a touch-sensitive antenna in its head. Unfortunately, if the antenna breaks or get lost you can’t praise him anymore. Now there is a replacement in clear resin 😉
Ok, it’s not an Aibo, but I like it and back it 😉
Nybble is a robotic cat that walks and built on an open source platform.
The aibo system.
The main software system runs on “Qualcomm Snapdragon 820”, Qualcomm Technologies for smartphones. The signals from the cameras and sensors, some of the output devices such as OLEDs (displays) and speakers are connected to the SoC. The motion processor controls the 22 axes of actuators and is connected to the local microcomputer board of each joint’s actuator via UART. The board controls the feedback of the actuator. (*)
The main board.
The large chip (in the middle left) is containing the Snapdragon 820 and 4-Gbyte DRAM Micron Technology Inc . The silver chip (right) is a 2.4GHz-band Wi-Fi module Murata Type1DR. The black chip (right) is for power supply. On the backside are 32-Gbyte flash memory and a chip for touch sensors Atmel Corp.
The motion processor board.
The two black long chips are level-shifter chips Toshiba Electronic Corp . The black square chip (right) is a motion processor RX631 32-bit Renesas Electronics Corp. It is connected to the feedback control boards for the 22 axes.
The Feedback control boards.
Feedback control for positioning each joint at each actuator. Each board has a 32-bit microcomputer for feedback control TXZ3 Toshiba Electronic Corp which is equipped with an Arm Cortex-M3 driver chip with a bridge circuit for motor driving DRV8313 Texas Instruments Inc.
The encoder boards.
They are magnetic type encoder for controlling the positioning of each joint.
